OBJECTIVE To evaluate the clinical usefulness of sonoelastography in infants with congenital muscular torticollis (CMT). METHODS The medical records of 215 infants clinically diagnosed with CMT were retrospectively reviewed. Fifty-three infants met the inclusion criteria as follows: 1) infants diagnosed as CMT with a palpable neck mass before 3 months of age, 2) infants who were evaluated ini...

Full-field quantitative strain maps of phase transformation and plasticity in Nitinol under large sheardominated deformation are presented. To achieve a sheardominated deformation mode with relatively uniform stresses and strains, a shear compression specimen (SCS) geometry was utilized. Shear deformation appears to impede the development of the strain localization during phase transformation t...

This report describes our initial in vitro results with roboticallyassisted strain imaging for intraoperative monitoring of hepatic tumor thermal ablation. First, we demonstrate a strong correlation between thermal ablation of liver tissue and changes in elastic properties. Second, we present an experimental environment to provide controlled robotically-assisted compression of liver tissue with...

INTRODUCTION Freehand ultrasound real-time elastography (RTE) is a simple technique allowing direct visualization of the elastogramme superimposed on the B-mode -image. The objective of RTE is to investigate stiffness and related parameters such as local tissue strain with a view to adding new information related to tissue morphology and architecture. MATERIAL AND METHODS This was a pilot stu...

In materials, the nature of the strain-stress relationship, which is fundamental to their properties, is determined by both the linear and nonlinear elastic responses. Whereas the linear response can be measured by various techniques, the nonlinear behavior is nontrivial to probe and to reveal its nature. Here, we report the methodology of time-resolved Kikuchi diffraction for mapping the (non)...
